Hello,

I have a Panorama with one Group (Group A) that contains a few tiles. I have changed the AllowDrag and AllowDrop for allow of these tiles to false to prevent Users from rearranging "Group A" tiles. At run-time, more groups and tiles are dynamically added based on individual user setting files. I am using the panorama.PanoramaElement.DragDropService.PreviewDragOver event to prevent users from dragging dynamically added tiles to "Group A".

First I get the position of the cursor on the Panorama using panorama.PointToClient(MousePosition). Then I get the left most Group (Group B) that is not "Group A" and set the EventArgs.CanDrop to false if the cursor is left of "Group B's" ControlBoundingRectangle.Left.

However, I found that if you drag a tile by first clicking on the right most edge of the tile and position the cursor just to the right of "Group B's" ControlBoundingRectangle's left edge, most of the tile hovers over the "Group A" but the cursor is within "Group B" and EventArgs.CanDrop is set to true. So when the user release the mouse, it puts the tile in "Group A".

I looked at panorama.PanoramaElement.DragDropService.PreviewDragDrop and the EventArgs.DropLocation.X was 165 when in the panorama.PanoramaElement.DragDropService.PreviewDragOver the panorama.PointToClient(MousePosition).X was 250 (under 250 is when EventArgs.CanDrop is set to false).

How can I determine if a tile is going to be dropped into "Group A" and cancel or prevent it?

IWorkbookFormatProvider and Telerik.Windows.Maths

Hi,

I deleted the Telerik.Windows.Maths dll from my project as I saw on another thread it was no longer required with the 2016 Q1 release. However, deleting it has caused it to stop my IWorkbookFormatProvider code from working (bringing up the 'Could not load file or assembly Telerik.Windows.Maths ...' etc. error), and obviously now, I can't re-download it. What should I do now?

Thanks for your help.

RadGrid sorting and dataset sorting

I have a radgridview which is bound to a dataset.
When the user sorts the radgrid, the dataset is not sorted equally so it does not give the correct data back for editing.

Is there a solution to that ?

[Solved] Read-only Columns/Rows/Cells

Is there a way to make specific columns, rows or even certain cells read-only in the grid on the side of the gantt chart. For example, I don't want users to be able to edit the name or dates of a task directly in the grid. Instead I want the user to have to double click on a line in the grid to bring up a window where they can edit those details.

Import rtf into radrichtextbox

Hi,

How can we import rtf into RadRichTextbox. We got the following code.

public RadDocument ImportDocx()

{

RadDocument document = null;

IDocumentFormatProvider provider = new DocxFormatProvider();

OpenFileDialog openDialog = new OpenFileDialog();

openDialog.Filter = "Documents|*.docx";

openDialog.Multiselect = false;

DialogResult dialogResult = openDialog.ShowDialog();

if (dialogResult == System.Windows.Forms.DialogResult.OK)

{

using (FileStream stream = new FileStream(openDialog.FileName, FileMode.Open))

{

document = provider.Import(stream);

}

return document;

}

But, it is not working. It is crashing while it tries to create the stream.

Please help us on this.

RadPrintDocument - Header Overlapping Content

Hi,

I'm having a problem with setting a header in a radprintdocument. I'm setting a leftheader only. It looks fine on the the first page, but on further pages, it prints on top of the content of the document -- as in, the content and the header start at the same point on the page, instead of the content being printed below the header.

Here's my code:

        Header = "Date: " & lblDateTime.Text & " To: " & txtTo.Text

        If txtCC.Text <> "" Then
            Header = Header & " CC: " & txtCC.Text
        End If

        Document.LeftHeader = Header
        Document.DefaultPageSettings.Landscape = False
        Document.DefaultPageSettings.PrinterSettings.Copies = 1
        Document.AssociatedObject = txtEmail
        Document.PrinterSettings.PrinterName = Printer

        Document.Print()
